AUTOMATIC LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 375,597. dated December2'7, 1887.

Application filed Juy 5. 1887. Serial No. 243.411. (No model.)

To aZZ whom, it may 0077087711.

Be it known that I, HEINRIOH'BILLETER, Jr, residing at Aschersleben,Kingdom of Prussia, German Empire, have invented new and usefulImprovements in Automatic Lubricators, of which the following is aspecification, reference being had to the accompanying drawings.

The present invention relates to apparatus for automaticallylubricatinginachinery,which apparatus is distinguished by its great simplicity ofconstruction and certainty of action.

In the accompanying drawings, Figure 1 is a front elevation of apparatusconstructed according to my invention. Fig. 2 is a section of the same,on the line 00 x, Fig. 1, and Fig. 3 is a side elevation, partly insection, on the line y 3/, Fig. 1.

This improved apparatus consists, essentially, of three principal parts,viz: The cylinder a, the driving piston or plunger 1), and mechanism fordisplacing these two parts relatively to each other. The cylinder isprovided with the stuffing-box a, and is closed at the lower end. Theflange a of the stuffing-box has a projection, 0, which moves in agroove,

0', formed in the frameof the apparatus. In-

stead of this projection and groove a longitudinal groove can be formedin the cylinder and a pin fixed to the frame caused to engage with thisgroove.

Upon the outside of the cylinder a, along its entire length, are formedscrew-threads, with which a nut, d, made in the form of a sleeve,engages. This nut turns in the socket e in the base 6 of the apparatus,and in order that no longitudinal displacement shall occur the sleeve isprovided at its upper end with a shoulder and at its lower end with anut, 66. The said sleeve is moreover provided at the upper edge withteeth d, with which the worm f engages. The said worm is firmlyconnected with its shaft, which is journaled in a block, at, capable ofswinging at its lower end upon a pivot, m, which is supported in lugs onthe base 6. The said block a is secured in position by the nut Z on ascrew attached to the base. If the nut is removed, the block a can beturned back so far that the worm f is disengaged from the teeth at. Uponthe shaft of the worm f, on one side of the block a, is a disengagedfrom the teeth d lever, 71,, which can reciprocate or swing back andforth upon the said shaft through the medium of any suitable device. Aratchetwheel, g, is likewise loose upon the shaft,with the teeth ofwhich ratchet-wheel g the pawl h on the lever it engages. A flat spring,12, is so fixed upon the shaft by means of a nut, p, that it must turnwith the shaft. The ends of the spring press upon one side of theratchetwheel 9.

The piston b of the apparatus is firmly connected at its upper end withthe cross-beam e of the frame, and is provided with an oil-cup, r, inthe bottom of which a cock, 0, is inserted. In the piston is formed alongitudinal hole, 8, which extends through the cock 0 and terminates inthe oil-cup r. A lateral opening also extends from the cock 0, to whichopening the oil exit pipe 8 is connected.

A vertical shaft, is, is supported at its lower end in the base of theapparatus, and is held near the upper end by an arm, 76". This shaftcarries a hand-wheel, k, and at the lower end is provided with aspur-wheel, i, which engages with the teeth d of the sleeve (1.

During every reciprocation of the lever h the. ratchet-wheel is turnedthrough a definite 7 angle, and thereby, also, through the medium of thefrictional spring 1), the shaft upon which is the wormf is turned,provided that the resistance opposed to the rotation is not larger thanthe friction between the spring 19 and the ratchet-wheel g. The rotationof the shaft f causes the sleeve d to turn, and this gradually moves thecylinder an upward, whereby the oil in the cylinder is pressed throughthe bore 8 of the plunger to the cock 0, and through the small pipe 8'to the part of the machine with which it is connected. \Vhen thecylinder has risen so high that the bottom of the same comes intocontact with the piston, the cylinder must be returned to its lowestposition and again filled with lubricating material. No breakage canoccur when the cylinder-bottom comes into contact with th e piston, asthe spring then slides on the surface of the ratchetwheel g, andtherefore no longer turns the wormf.

For the purpose of filling oil into the cylinder the screw Z is removedand the worm f is The cylinder can then be moved more quickly downwardby means of the hand-wheel 7c and the wheel 6 than would be possible byturning the ratchetwheel back.

When moving the cylinder downward, the cock 0 is turned so that the'pipe 8' is closed and the oil-cup r, into which the necessary oil ispoured, is in connection with the interior of the cylinder.

What I. claim is 1. In lubricating apparatus, the combination of thepiston I), provided with a longitudinal passage, the cylinder a, adaptedto be Wmoved on the said piston by means of a thread out upon its outerperiphery and a nut, d, the turning of the said cylinder being preventedby a longitudinal groove and a projection engaging with the said groove,a worm, f, acting upon the nut d, and the ratchet-wheel 9, all for thepurpose of pressing the lubricant through the saidv longitudinal passagein the piston, essentially as described and represented.

2. The combination, with the piston b, having a longitudinal passage,the non-rotating screw-threaded cylinder a, the nut d, the worm f,acting on the nut, and the ratchet-wheel g on the shaft of the Worm, ofthe Hat spring p, firmly secured to the worm-shaft and sliding upon theratchet-wheel when the resistance becomes too great, substantially asand for the purposes described.

In witness whereof I have signed the foregoing specification this 24thday of May, 1887.
